That's not exactly true. People tend to put spammers on their ignore list, and when someone is ignored their post (and their signature as well) doesn't show up in a thread. So a campaign full of spammers is receiving less exposure than a campaign with no spammers, because chances are lots of people will be ignoring the spammers. Plus, having a campaign full of spammers doesn't give the advertised website a good reputation. I'm not inclined to use YoBit or recommend it to others, partially because of how they manage their signature campaign. It seems that they don't really care about the Bitcointalk community, because of how irresponsible they are when it comes to spammers in their signature campaign. If they can't properly manage a signature campaign, how can I trust them with my crypto?
